     2. Nền tảng (reset, chữ, focus)        7. Header, trình đơn điện thoại, footer
     3. Bố cục (.wrap, .section)            8. Khối trang chủ (hero, dịch vụ, đào tạo, việc làm, giới thiệu, chia sẻ, liên hệ)
     4. Kiểu chữ display (.t-*)             9. Trang trong (.phero, .crumbs, .missing, .prose)
     5. Họa tiết (vát góc, sọc cảnh báo, lưới bản vẽ, đường kích thước, số viền)
